20080198024 | Capacitance-based occupant detection system and occupant protection system - A capacitance-based occupant detection system accurately determines seat occupancy and a failure of an electrode and between electrodes and includes an impedance calculation section, a Re/Im part calculation section, and a determination section. A first impedance Z | 08-21-2008 |
20090015390 | Collision-detecting device for automotive vehicle - A device for detecting a collision of a vehicle with an obstacle includes an enclosed space positioned behind a front bumper cover. Deformation or displacement of the bumper cover due to a collision is transmitted to the enclosed space. Air pressure in the enclosed space and its temperature are measured by sensors and electrical signals representing the pressure and the temperature are fed to an electronic control unit that determines whether the enclosed space is hermetically closed or not based on the pressure and the temperature of the air in the enclosed space. If the enclosed space becomes non-hermetical due to a collision impact, the air therein leaks and the pressure therein becomes atmospheric pressure irrespective of the temperature of the air in the enclosed space. Therefore, the hermetical condition of the enclosed space is surely detected. | 01-15-2009 |
20090015391 | Collision detection sensor for vehicle - A chamber room is located between a bumper reinforcement and a bumper cover in a vehicle front-rear direction. The chamber room is deformed with a relative movement of the bumper cover to the bumper reinforcement in the event of the collision. A pressure sensor is located in the chamber room to detect a pressure change in the chamber room. A touch sensor is located between the bumper reinforcement and the bumper cover to detect contact with the bumper cover. The touch sensor and the chamber room are located at different positions in a vehicle top-bottom direction. It is determined whether collision occurs based on the detection results of the pressure sensor and the touch sensor. | 01-15-2009 |
20090020353 | Vehicular collision detection apparatus - A collision detection apparatus for a vehicle includes a bumper reinforcement, a chamber forming member, a pressure sensor, collision object determining unit, and a collision position sensor. The bumper reinforcement is mounted on the vehicle and extends in a transverse direction of the vehicle. The chamber forming member is provided at a side of the bumper reinforcement and defines a chamber space that is deformable when the object collides with the vehicle. The pressure sensor detects pressure in the chamber space. The collision object determining unit determines a category of the object by comparing the pressure detected by the pressure sensor with a predetermined determination threshold value. The collision position sensor detects a transverse position, at which the object collides. The determining unit changes the determination threshold value based on the collision position detected by the collision position sensor. | 01-22-2009 |
20090021029 | Vehicular collision detection apparatus - A vehicular collision detection apparatus includes a bumper reinforcement, a bumper cover, a chamber forming member, a pressure sensor, a pressure changing device, and a chamber state detecting device. The cover is displaceable relative to the reinforcement toward a rear of the vehicle upon collision. The chamber forming member is provided between the reinforcement and the cover and defines a chamber space that is deformable upon displacement of the cover. The pressure sensor senses pressure in the chamber space. The pressure changing device changes pressure. The chamber state detecting device detects whether or not the chamber forming member is broken based on the pressure, which is detected while the pressure changing device is in operation. | 01-22-2009 |
20100121521 | Electronic safing system - The electronic safing system is provided with a safing sensor, a comparator, and a microcomputer. The microcomputer has a programmable analog I/O port which is connected to a built-in AD-DA converter. The programmable analog I/O port can be switched to an analog input port and an analog output port according to an internal register. The programmable analog I/O port is connected to an input terminal of the comparator. When diagnosing the comparing circuit, the microcomputer switches the programmable analog I/O port to the analog output port and outputs a predetermined voltage for diagnosis. Then, the microcomputer diagnoses the comparing circuit by monitoring the output of the comparing circuit. | 05-13-2010 |
